TSV vs TXT
A detailed comparison of TSV (Tab-Separated Values) and Plain Text — file size, quality, compatibility, and which format to choose for your workflow.
TSV (Tab-Separated Values)
Spreadsheets & DataTSV uses tabs instead of commas to separate values in tabular data. It avoids quoting issues common in CSV when data contains commas, making it popular for scientific and linguistic data.
About TSV filesPlain Text
Documents & TextTXT files contain unformatted plain text with no styling, images, or layout information. They are universally readable by any device and operating system, making them the simplest document format.
About TXT filesStrengths Comparison
TSV Strengths
- No quoting needed — tabs in data are astronomically rare.
- Simpler parser than CSV.
- Preferred by databases, bioinformatics, and scientific pipelines.
- Opens cleanly in every spreadsheet app.
- Plain text, grep-friendly, diffable.
TXT Strengths
- Universally readable — every operating system, every editor, every programming language.
- Zero metadata overhead: the file size equals the character count (for ASCII).
- Safe to diff, grep, version-control, and pipe through command-line tools.
- Immune to format obsolescence: a text file from 1970 still opens today.
- Tiny footprint for structured data like logs or configuration.
Limitations
TSV Limitations
- Tabs can be invisibly replaced with spaces by text editors.
- Carriage returns inside fields require escaping conventions.
- Less ubiquitous than CSV in business/consumer workflows.
- No metadata, no schema, no type information.
TXT Limitations
- No styling, images, or embedded structure — just characters.
- Character encoding ambiguity (ISO-8859-1 vs UTF-8 vs Windows-1252) causes "mojibake".
- Line-ending differences between OSes still cause subtle bugs today.
- No way to carry hyperlinks, tables, or formatting without a convention on top (like Markdown).

Frequently Asked Questions
TSV (TSV (Tab-Separated Values)) is a spreadsheet format used to store tabular data in rows and columns, typically with multiple sheets per workbook, cell formatting, formulas, and optional charts. It is part of the spreadsheets & data family and is the native format of a specific spreadsheet application.
TXT (Plain Text) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.
Excel, Google Sheets, LibreOffice Calc, and Apple Numbers handle most TSV files with high fidelity. For simple one-off viewing, Google Sheets and the Office web apps open TSV in the browser without installing anything. Convert to XLSX or CSV first if your target tool is strict about formats.
Modern office suites — Microsoft Word, Google Docs, LibreOffice Writer, Apple Pages — open most TXT files with reasonable fidelity. If your installed software does not support TXT, convert to DOCX or PDF first using KaijuConverter; both open in virtually every reader, including free online viewers.
Upload the TSV to KaijuConverter and pick XLSX, CSV, ODS, TSV, or PDF. Our LibreOffice-based pipeline reads the sheet data, preserves cell types (numbers, dates, strings), and writes a clean target file. Multi-sheet workbooks come back as a single multi-sheet export or a ZIP of per-sheet CSVs depending on target.
When converting between spreadsheet formats that support formulas (XLSX, ODS), formulas transfer with function-name translation. When converting to CSV, formulas resolve to their cached evaluated value (open the source in Excel once to force evaluation if you suspect stale cache).
